Predation, reproduction, and development of the lady beetle Hippodamia convergens (Coleoptera: Coccinellidae) Introduction: Keeping populations of predatory insects in the agroecosystem by offering them prey, as well as food resources from plants, is important for enhancing conservation biological control. Objective: To determine if the consumption...

Spittlebug (Hemiptera: Cercopidae) species cause large economic losses on gramineous crops (Poaceae) in tropical and subtropical America. These insects are key pests of sugarcane and forages, crops that experienced a quick expansion in extensive monocultures in Brazil, Colombia, and Mexico. Mobilization toward sustainable crop and livestock systems...

Prodiplosis longifila Gagné (Diptera: Cecidomyiidae) is a pest that feeds mainly on Solanaceae, Rutaceae and Asparagaceae crops in Colombia, Ecuador and Peru (Hernandez et al. 2015) and it was recently reported feeding on Jatropha clavuligera in Bolivia (Dhileepan et al. 2017). Biological control of P. longifila in Colombia is incipient and based o...

Biological control with arthropods often focuses on understanding the relationship between the pest and the biological control agent. However, a community of insects and non-cultivated plants that surround the target crop help to suppress pests as they interact and may exploit different or similar resources. Using as a study model commercial crops...

Viral diseases, transmitted by aphids, are the most limiting problems in chili pepper crops. Understanding the demographic features of these aphids, may thus assist the design of better disease control strategies in chili peppers. Aphid species found in chili pepper crops in southwestern Colombia were identified as Aphis gossypii Glover and Myzus p...

Chapter
The history of biological control of agricultural pests in Colombia dates back to 1880. The first documented cases include both classical biocontrol and the use of biopesticides against insect pests. The need to protect four national production systems of great economic importance (oil palm, sugarcane, coffee and greenhouse flowers and vegetables c...

Prodiplosis longifila is reported as a pest of a wide range of species cultivated in America, including citrus, solanaceous species and asparagus. This species has different behavioural traits that are primarily centred on the oviposition habit and the feeding of larvae, which can change depending on the host. However, scarce information is availab...

Cryptic species complexes have rethought the traditional concepts and ideas about ecological specialization. Research on herbivores of the class Insecta using molecular markers showed that although they are alleged generalists in their diet, they are complex specialists in narrow host ranges. In Colombia, Prodiplosis longifila Gagné, 1986 (Diptera:...

There is an increasing evidence that populations of ectotherms can diverge genetically in response to different climatic conditions, both within their native range and (in the case of invasive species) in their new range. Here, we test for such divergence in invasive whitefly Bemisia tabaci populations in tropical Colombia, by considering heritable...

Abstract. A non-human primate model for the induction of protective immunity against the pre-erythrocytic stages of Plasmodium vivax malaria using radiation-attenuated P. vivax sporozoites may help to characterize protective immune mechanisms and identify novel malaria vaccine candidates. Immune responses and protective efficacy induced by vaccinat...

Vaccine development for Plasmodium vivax malaria is underway. A model to assess the protective efficacy of vaccine candidates in humans is urgently needed. Given the lack of continuous P. vivax cultures, we developed a system to infect Anopheles albimanus mosquitoes using blood from P. vivax-infected patients and determined parameters for challenge...
